She has said she wants to lose 30lbs in her constant battle of the bulge.

And actress Kirstie Alley revealed why as she left the Crosby Hotel in New York City on Wednesday - after provoking a row over the term 'circus fat' in her first advert for the Jenny Craig weight loss programme.

The 63-year-old covered up her heavier frame in a shiny, bronze-coloured coat worn over a clinging black v-neck dress and leggings.

She slipped her red-painted toes into square-heeled sandals with one gold strap across her foot and another cradling her heel and ankle.

The Cheers favourite wore her signature long blonde tresses loosely around her face, which was minimally made-up for day wear with light foundation, a dab of blusher and a splash of coral lipstick.

The celebrity checked her cell phone as she walked along, peering through her brown-rimmed sunglasses.

Riding out the storm: The 63-year-old caused consternation in her first advert for the Jenny Craig wight-loss programme when she joked: 'I'm not circus fat but I need to lose weight'

Kirstie's first Jenny Craig commercial, released on Monday, upset some viewers after she joked: 'I'm not circus fat but I need to lose weight.'

The advert prompted a flurry of tweets that forced her to explain the term 'circus fat' in interviews with Matt
Lauer on Today and the Rachael Ray show, due to air on April 21.

Kirstie insisted she didn't mean to be offensive.

Offering support: Rachael said she felt critics were being a little too sensitive over her self-deprecating humour

'I grew up
in an era where my dad would take me to the fair and to the circus and
they actually had fat ladies in the circus,' Kirstie told Rachael.

The Veronica's Closet actress added: 'I am talking about myself (in the advert). So I think I can call myself whatever I want to call myself.'

'You're literally being self-deprecating. You can say whatever you want,' Rachael, 45, added.

Circus days: Kirstie said her father took her to a circus when she was a child and the fat lady was an attraction

Kirstie lost 75 lb with Jenny Craig back in 2004 and maintained her 145 lb weight with the company until she left in 2007.

She
lost an incredible 100 lbs on her own Organic Liaison weight-loss plan
in 2011 and by working out for Dancing With The Stars, but the weight
came back after the dancing show ended.

Kirstie
now will be sticking to Jenny Craig meals along with supplements from
her Organic Liaison line, which will also be sold at Jenny Craig
centers.

Back to basics: Kirstie's new Jenny Craig TV ad aired on Monday after an earlier announcement that she was rejoining the weight loss company she had represented from 2004 to 2007
